Hey all,
I see plenty of drag and drop examples but they are all for
wx.ListCtrl. Anyone know of examples or tutorials for wx.ListBox?
Specifically, I would like to be able to drag a selection from one
ListBox to another.
Thanks in advance,

class MyFrame(wx.Frame):

wx.Frame.__init__(self, None, -1, "List Boxes")
panel = wx.Panel(self, -1)
choices1 = ["red", "green", "blue"]
choices2 = ["10", "20", "30"]
self.lb1 = wx.ListBox(panel, -1, (10, 10),
(100, 200), choices1, wx.LB_SINGLE)
self.lb1.Bind(wx.EVT_LISTBOX, self.on_select)

(100, 200), choices2, wx.LB_SINGLE)

if drop_result == wx.DragMove: #the selection was moved-not
copied
self.lb1.Delete(selection)

def __init__(self, target_widget):
wx.TextDropTarget.__init__(self)
self.target_widget = target_widget
self.text_obj = wx.TextDataObject()
self.SetDataObject(self.text_obj)
def OnData(self, x, y, default): #called automatically on drop
self.GetData()
text = self.text_obj.GetText()
end_of_list = self.target_widget.GetCount()
self.target_widget.InsertItems([text], end_of_list)
return default
app = wx.PySimpleApp(redirect=False)
win = MyFrame()
win.Show()
app.MainLoop()
